Mortality rate (significant at P< 0.05 level), X concentration (significant at P< 0.05 level), LC50 lethal concentration that kills 50% of the exposed larvae, LC90 lethal concentration that kills 90% of the exposed larvae, SE standard error (all values are mean of four replicates), LCL lower confidence limit, UCL upper confidence limit
